91125018 divided by 611 
The aim is to understand the frequency of 611 in 91125018.

Let's proceed to step 1:
If we divide 9 by 611, we get 0 and a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 611

Moving on to step 2:
91 divided by 611 is 0 with a remainder of 91.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 91 to get 91.
Append the next digit (1) from the dividend to 91 and continue with: 911 / 611

Moving on to step 3:
611 can be fit into 911 1 times, resulting in a remainder of 300.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 611 from 911 to get 300.
Take the next digit (2) from the dividend and append it to 300, then repeat: 3002 / 611

Step 4:
611 can be fit into 3002 4 times, resulting in a remainder of 558.
Use 4 as the next digit of our solution. 
Result so far: 14.0
If we take 2444 away from 3002, we end up with 558.
Grab the next digit (5) from the dividend, add it to 558, then carry on: 5585 / 611

Going ahead to step 5:
When dividing 5585 by 611, we get 9 with a remainder of 86.
The number 9 becomes the next digit in our result. 
Result so far: 149.0
The remainder is 86 after subtracting 5499 from 5585.
Include the next digit (0) from the dividend after 86, then repeat: 860 / 611

Moving on to step 6:
When dividing 860 by 611, we get 1 with a remainder of 249.
Use 1 as the next digit of our solution. 
Result so far: 1491.0
Subtracting 611 from 860 leaves us with 249.
Take the next digit (1) from the dividend and append it to 249, then repeat: 2491 / 611

On to step 7:
611 goes into 2491 4 times with a remainder of 47.
The number 4 becomes the next digit in our result. 
Result so far: 14914.0
Subtract 2444 from 2491 to get 47.
Fetch the next digit (8) from the dividend, attach it to 47 and continue: 478 / 611

Advancing to step 8:
If we divide 478 by 611, we get 0 and a remainder of 478.
Use 0 as the next digit of our solution. 
Result so far: 149140.0
Subtract 0 from 478 to get 478.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4780, and continue the process.

Advancing to step 9:
When dividing 4780 by 611, we get 7 with a remainder of 503.
Use 7 as the next digit of our solution. 
Result so far: 149140.7
If we take 4277 away from 4780, we end up with 503.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5030, and continue the process.

Moving on to step 10:
611 goes into 5030 8 times with a remainder of 142.
Use 8 as the next digit of our solution. 
Result so far: 149140.78
Subtracting 4888 from 5030 leaves us with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Advancing to step 11:
611 can be fit into 1420 2 times, resulting in a remainder of 198.
Use 2 as the next digit of our solution. 
Result so far: 149140.782
If we take 1222 away from 1420, we end up with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Let's proceed to step 12:
When dividing 1980 by 611, we get 3 with a remainder of 147.
The number 3 becomes the next digit in our result. 
Result so far: 149140.7823
If we subtract 1833 from 1980, we get 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

On to step 13:
611 goes into 1470 2 times with a remainder of 248.
Record the quotient 2 as the next digit in the result. 
Result so far: 149140.78232
Deduct 1222 from 1470 and we're left with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Moving on to step 14:
611 goes into 2480 4 times with a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 149140.782324
If we subtract 2444 from 2480, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 15:
The number 611 fits into 360 0 times, leaving a remainder of 360.
Use 0 as the next digit of our solution. 
Result so far: 149140.782324
If we subtract 0 from 360, we get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Advancing to step 16:
611 goes into 3600 5 times with a remainder of 545.
Record the quotient 5 as the next digit in the result. 
Result so far: 149140.78232405
The remainder is 545 after subtracting 3055 from 3600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5450, and continue the process.

The final outcome is 149140.78232405, with a leftover of 5.45e-07.
